Rebuild Python application from existing executable (original developer not available)

Job ID: 39858981

Budget: ₹12,500 – ₹37,500 INR

I have a Windows-based Python application that was originally developed for my business.
The original developer is no longer available and did not provide the full source code.

I need an experienced Python developer who can:

Analyze the existing packaged or compiled version of my software.

Understand its structure and behavior.

Rebuild a clean and runnable Python project with the same functionality.

Provide documentation and setup instructions.

This is a legitimate rebuild of my own software for which I have full rights and ownership.
An NDA (Non-Disclosure Agreement) and IP transfer confirmation will be required before sharing any files.

Please include:

Relevant experience with packaged Python apps (e.g. PyInstaller, cx_Freeze, Nuitka, etc.)

Timeline and fixed price quote.

A short note confirming you understand this project is for recreating an owned application.

Thank you!
